Important Update: Expansion of the Battery Safety Recall and Replacement Program for HP Notebook Computers and Mobile Workstations announced in January 2018 – Additional Batteries Affected

 

HP urges customers to recheck all potentially affected products

 

In cooperation with various government regulatory agencies HP has announced an expansion of its worldwide voluntary safety recall and replacement program for certain notebook computer and mobile workstation batteries announced in January 2018. The potentially affected batteries may have been shipped with certain HP notebook computers and mobile workstations sold worldwide from December 2015 through April 2018.

 

The batteries have the potential to overheat, posing a fire and burn hazard to customers.  It is essential that you check or recheck your battery, even if you did so previously and were informed that it was not affected.

HP’s primary concern is for the safety of our customers. Because these batteries pose a fire and burn hazard, it is essential to visit the HP Battery Recall website at www.hp.com/go/batteryprogram2018 as soon as possible and check your battery.

Battery will not charge when system is warm to hot

If the “not charging” issue is (only) apparent when the system is running hot (or near that point), the battery and charge system are likely overheated as well – the charge system will resume operation when the computer cools down.  Short Version:  An overheated battery / computer / charging-system will not charge the battery – this is normal behavior.

 

 

Battery seems “stuck” in a particular charge setting                                                                  

The battery might be OK and just need calibration (balance / set).

ac adaptor not charging

hi dragon-fur, many thanks. I had checked out the recall on batteries, tested charger etc. this is to do with an update that started in September this year. I found the solution after some hunting around HP help (seems it's a fault in updates on windows 10 they are aware of ) and to do the repair the steps are - device manager - batteries, un-install (Microsoft ac & Microsoft acpi) - shut down laptop - un-plug - wait 5 minutes - remove & replace battery - plug in - power up. batteries in device manager re-install automatically. HP help also says to search for latest bios update through their site - my computer says I've got it, so that was no help. not being a savvy computer person, took ages to figure it out to start with.  I've now tried turning of auto updates, opted for choosing the ones I want. however, as I've not got a scuby which update has the error have to wait for next updates and check them one at a time. it's happened 4 times now. what a palava just because someone who supposedly knows what they are doing messed up. i'd get sacked if I kept messing up like this.

ac adaptor not charging

@jeanydo 

 

Excellent.

You are welcome,

And

Thanks for posting back your solution,

 

The method has been around at least since 2011 and I found a couple of references to Windows 7, for example, that provide the same fix. Based on what I can find on the subject, this appears to be most generally a Windows "thing" and not closely associated with the brand of computer.

 

I agree that it would be real nice if this method worked for everyone (or at least more people with battery problems) and, because the fix has been around for so long, that the fix was more visibly available without all the hunting, guessing, and looking.

 

Well, done.
